The focal length is 12.5 mm.
The lenses are chemically brightened.
Mounting М32х0,5 /31.
Mir-11 12.5mm f2 - wide-angle lens from the 16mm movie camera "Kiev-16U".
It should not be confused with the Mir-11 2/12.5 lens from the Krasnogorsk movie cameras.
The lens also has a modification of the Mir-11M 2/12 with a modified appearance from the movie camera "Kiev-16UE"
Without reworking it is suitable for Pentax Q, Black Magic.
On the Nikon 1 a little vignette, but not catastrophically, so the alteration is also not needed.
On the Micro 4/3, you need to unscrew the built-in lens hood, or maybe cut the diaphragm setting ring.
On the APS-C is not suitable - too strong vignetting.
